.Thrashingand Separating Grain, of which the following is a full, clear, and exactdescrip tion 'of the same, reference being had to the accompanying drawings, which makepart of this specificatiom and in which-- y g V Figure .1 represcntsa view in elevation of onesifde. of amaehine fortll fifilli' g and .slcn

; arating grain embracing .my improvements,

portion of the frame-work being broken' away to show the mechanism within. Fig; 2 represents a plan or top view of the same, with the" grain-belt, straw-carrier, and covering removed, a'nd the casing of the" cylinder thrown back upon its hinges. Fig. 3 represents a vertical longitudinal section -.throughthe same at the line as a; of Fig.2 with the covering-belts, and casing in position,

. The improvements claimed under this patent consist, firs t, in forming anindependent frame inside the g ia'in-belt frame, as hereinafter described, thereby providinga space between them in which to locate the driving-1 pulleys and winn'owing-spouts; second, in combination with the double frame above described, driving the grain belt, straw-carrier, beater, and picker' from thej conveye'r-shaft, whereby their driving-bands are kept inside the framing. 4

In the accompanying drawings, which rep resent a convenient arrangementot partsfor carrying out the objects of my invention, the mechanismis shown as mounted in a stout frame, A. Inside of the grain-belt frame'B a smaller-frame 'or trough, B", is arranged, as shown. in Figs. 2 and 3 of the drawings, so that a space, 1), is leftxbetween the .twoon each side. It will be observed that rollers of;- the grain-belt: and straw-carrier, t'hebeater shaft and the picker, all turn in bearings driven by acord, i, encircling a pulley, e, on-

the counters hafti Ely Ihe beater J is driven in" asimilar manner from the conveyer-shaft b'ya c'ord,' :T th e grain belt-K by a cord, In, the fitlfflrli rcarrier L b a cord, l, and the picker,

shaft Mf'bya cord.,-m.i By this arrangement all the; mechanism, except the cylinder,is-

driven from the convey e'r-s haft, while the belts and pulleys are kept inside the frame-Work,

whereithey are protected from the weather.

The machine is likewise .to be providedwith a suitable shaking-shoe oririddle;

,Itis deemed unnecessaryheretodescrihej in detailthe construction and operation of the other parts of the mechanism, as they form no part ofthe subject-matter herein claimed, and, besides, are fully described; in two other applications filed simultaneouslywith this, and

marked, grespectively, Division F-and H,

What-Ll; claim under this patent as my in vention is- '1; Constructing an independent frame or" trough inside thefgrain-bclt frame, snbsta n' tially in the .m'anner des'cribed,"so as to form a space in which to'locatethe driving-pulleys,

2. In combination with an independent frame, driving the grain-belt, straw-carrier, heater,- and picker-front the conveyer-sl aft,

substantially in the manner and forthe pur pose described;

In testimony whereofl have hereunto sub- 7 scribed my name; v
